windowBits of 16 means "decode gzip header" and "use window size
from zlib header". For some reason, this results in a window size
that is too small on OpenBSD. Instead, use maximum window size
explicitly, since there is no downside for doing so.
Not everyone knows how to check out the sources with git (or that
we require that, because of submodules), and has the basic build
tools like gcc installed, so point that out explicitly.
Since font sizes in SolveSpace are specified in terms of cap height,
we need U+0041 to determine cap height. Some fonts lack it; in
that case, we assume that cap height is the same as the size we've
requested. This avoids a crash, at the cost of completely wrong
(although consistent) metrics; I do not really know of a better way.
There was a copy rule that copied the locale from the source
to the binary directory, and also a regeneration rule that used
the locale in the binary directory as a temporary file.
Rename the target for the latter.
To reproduce:
* New sketch;
* Create two redundant constraints, with second being automatically
marked as reference;
* Switch one of these to non-reference;
* Allow redundant constraints;
* All new constraints with labels created as reference, even
if that specific degree of freedom is not constrained yet.
Before this commit, if the source group of a step rotate/translate
group is forced to triangle mesh, the UI would show that the step
rotate/translate group is also forced to triangle mesh, but the group
would in fact contain NURBS surfaces.
glibc defines a CHAR_WIDTH macro in limits.h since about 6.3.*.
This is apparently added as a part of ISO TS 18661-1:2014, which
I cannot read because it is not publicly available, and which covers
some sort of floating-point extensions. This is one of those changes
that should never have been done yet here we are.
This commit updates a *lot* of rather questionable path handling
logic to be robust. Specifically:
* All path operations go through Platform::Path.
* All ad-hoc path handling functions are removed, together with
PATH_SEP. This removes code that was in platform-independent
parts, but had platform-dependent behavior.
* Group::linkFileRel is removed; only an absolute path is stored
in Group::linkFile. However, only Group::linkFileRel is saved,
with the relative path calculated on the fly, from the filename
passed into SaveToFile. This eliminates dependence on global
state, and makes it unnecessary to have separare code paths
for saved and not yet saved files.
* In a departure from previous practice, functions with
platform-independent code but platform-dependent behavior
are all grouped under platform/. This makes it easy to grep
for functions with platform-dependent behavior.
* Similarly, new (GUI-independent) code for all platforms is added
in the same platform.cpp file, guarded with #ifs. It turns out
that implementations for different platforms had a lot of shared
code that tended to go out of sync.
Extrustion top and bottom faces require a normal to be present.
Before this commit, the normal is always taken from the assembled
loop; if the loop could not be assembled (i.e. the loop is broken
or not coplanar) the normal will be (0,0,0), which breaks the sketch.
Also, loops are not generated when generating the sketch
to determine its bounding box.
This may result in spuriously broken sketches when e.g. undoing
a change that has broken a loop.
After this commit, loops are generated when generating for bounding
box, and if the loop could not be assembled, then the workplane
normal is used. This still results in failures when there is
no workplane, but those cases should be quite pathological.
Before this commit, a same orientation constraint created with
a workplane selected would only remove 2 of 3 DOFs. After
this commit, it properly removes all 3 DOFs.
